Alcohol Gas Sensor Arduino

This sensor has a long life and good sensitivity.

Alcohol gas sensor arduino.

The alcohol sensor we will use is the mq 3 sensor. This is a sensor that is not only sensitive to alcohol particularly ethanol which is the type of alcohol which is found in wine beer and liquor. In this project we will go over how to build an alcohol sensor with an arduino. We know mq3 alcohol sensor is suitable for detecting alcohol concentration in air or from the breath this gas sensor interfacing circuit can be used as breathalyzer.

A breathalyzer is a generalized trademarked name for devices used for determining blood alcohol content from a breath sample. To design this arduino alcohol project circuit we have chosen the online eda tool called easyeda. Smoke detection using mq 2 gas sensor. The alcohol gas sensor we used is the mq 135 sensor.

Hi guys welcome to this tutorial. Here simple arduino alcohol sensor code is written to interface mq 3 gas sensor alcohol with arduino board in this case we used arduino uno board. Some of the applications that can be made by using this sensor are alcohol gas alarm portable alcohol detector gas alarms breathalyzer etc. You ll learn how to use the ky 037 sound detection sensor with arduino.

Today we will build a breathalyzer using the mq3 gas sensor an oled display and arduino. Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display. Mq 3 alcohol sensor circuit built with an arduino. Detect the presence of alcohol with arduino.

Circuit and pcb design using easyeda.
